Is it possible to have the original label (or button) text displayed below the label field permanently (serving as a description of the purpose of the label (or button)? The text shown inside the field is overwritten when the label text is changed. Of course, a second label could do it, but potentially there is a direct way.
A label or button can only have one text field, they could be multiline, but you would have to maintain the second line whenever you change the text, the simplest way would be to add a second label and copy the original text to that when it's changed.
